Title: Improvements in and relating to Electric Hot-Plates
Inventor: URRY JOHN THOMAS
IPC: F24C15/10
Filed: 1965-06-21
Abstract: 1,150,343. Temperature responsive actuating elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 20, 1966 [June 21, 1965], No.26146/65. Heading G1D. [Also in Division H5] A solid electric hot-plate 1 with a temperature controlling arrangement has the temperature sensing element 5 carried by a flanged heat conducting ring 8 in an aperture in the hot-plate 1 and biased such that when a vessel is not on the hot-plate the flanged portion 8b of ring 8 contacts directly with the underside 1c of plate 1 such that element 5 responds to the temperature of hotplate 1 itself and when a vessel is on hot-plate 1 element 5 is in contact with the vessel and flanged portion 8b is separated from the underside of plate 1 such that element 5 then responds to the temperature of the vessel. Element 5 is biased upwardly by spring 11 formed by capillary conduit from element 5 connecting the capsule with an expansible bellows as described in Specification 995, 237. The hot-plate comprises a cast plate 1 sealed to a caster bob 2 by sealing ring 2a containing electrical resistance wire heating element 3 insulated with ceramic 4 in channels 1b. The central hole through which element 5 projects is sealed to plate 1 by a ring seal 6 of fluoroelastomer material to prevent spillage entering the hole but allowing vertical movement of element 5.

Title: Multilayer printed circuit boards
IPC: H05K1/02
Filed: 1975-06-20
Abstract: 1501500 Printed circuits INTERNATIONAL COMPUTERS Ltd 14 June 1976 [20 June 1975] 26256/75 Heading H1R In a multilayer printed circuit board an insulant layer 1 carries conductive layers 2, 3 on opposed faces forming power supply and screening planes and an insulant layer 4 is superimposed on layer 3. Thereon are placed mutually orthogonal groups of parallel conductors 5, 7 separated by insulant layer 6 which are formed by etching out a copperclad laminate. A further insulant layer 8 overlies conductors 7, on the exposed face of which a further pattern of conductors 9 is formed by deposition to determine a required circuit. Interlayer connections as required by the circuitry are provided by plated through holes of the insulant layers, e.g. at 10, connecting layer 2 to conductor 51 of group 5, with a clearance hole 3 isolating from layer 3 and at 11 connecting conductive layer 3 to a superimposed conductor (not shown) with conductor 52 of group 5 broken away for isolation. Other interlayer connections may be provided, e.g. at 12 between conductor 54 of group 5 and conductor 71 of group 7 with conductors 54, 71 broken away at 55, 72 for isolation. A complex circuit may thus be built up on multilayer boards, with external connections, e.g. 9, between pads 91 of the through hole connections. Other plated through holes provide solderable connections for mounted components with flying leads, e.g. an integrated circuit 21 with plural leads 22 engaging through holes 23 connected to interconnection pads 92, interlayer connectors 13 and, e.g., internal conductors 73. The conductors 5, 7 thus form transmission lines screened by planes 2, 3 held at steady D.C. potentials; the conductors having differing characteristic impedances. Balance is restored by modifying the configurations of the circuit patterns of the outer surface to provide increased areas. Thus interconnection pads 92 are increased in area to be oval, and further areas 93, 94 of conductive material may be provided which are isolated from the circuitry and connected to one or other of the conductive planes 2, 3. Area 93 is of wavy edged T form interpolating between plated through holes 96 of a row, while area 94 comprises interconnected circular pads interpolated between groups of through holes 96. The interconnecting links are selectively severable for final matching adjustment.

Filed: 1972-06-06
Abstract: 1431431 Polymer-modified bitumen TARMAC ROADSTONE HOLDINGS Ltd 1 June 1973 [6 June 1972] 26258/72 Heading C3N A method of making a polymer modified bitumen material comprises the steps of forming a solution of a polymeric material in a solvent, both the solution and the solvent being solid at ambient temperature and the solution being miscible with bitumen when melted, and mixing the solution with bitumen which has been heated to a sufficiently high temperature to melt the solution. The solvent is preferably naphthalene and preferably the solid solution is of a concentration such that the melting point of the solid solution is approximately equal to that of the bitumen. The polymer is preferably a styrene-butadiene-styrene block copolymer. In the specific example a solid solution is formed from a mixture of naphthalene and styrenebutadiene-styrene copolymer (1 : 1) subsequent to which 50 grams of this solution is mixed with 450 grams of 50% bitumen heated to 110‹ C. If it is desired to coat an aggregate such as stone chippings the solid solution is introduced with the bitumen into a mixer together with the aggregate.

Filed: 1925-10-22
Abstract: 241,921. Mackensen, O. Oct. 22, 1925. No Patent granted (Sealing fee not paid). Camera lucidas. - A reflector system is used in conjunction with keyboard apparatus, e.g. pianos and typewriters, to enable the keys to be seen at the same time as the manuscript, and to render a change in the direction of vision unnecessary. In one example, Fig. 1, a sem-trasparent reflector a and a reflector b are supported on a frame f so that direct vision of the manuscript e is obtained through the reflector a and a reflected erect image of the keys d is presented to the eye c. The reflector b may be cylindrically convex to embrace the whole keyboard. A second example, Fig. 3, produces the same result, by means of two mirrors a, b, mounted in a frame carried on the head of the observer, the image of the keys f being observed in the mirror a reflected from the mirror b, as shown. The invention is stated to be applicable also to calculating- machines, motor-cars and aircraft, in the latter two instances to permit the driver to see any indicating apparatus without altering his line of vision from direct ahead. Specification 17837/92 is referred to.
